| Abstract: | Taking the negative feedback with voltage series as an example, the load effect of feedback network is analyzed quantitatively by employing the generalized h parameter of transistor. The application conditions of general expression for the amplified multiple of negative feedback amplifier are obtained, and meanwhile emphasizing that the feedback coefficient has nothing to do with the inner resistance of signal source and load resistance. |
